BELL-RINGING DEVICE.

SPECIFICATION forming part of Letters Patent No. 652,465, dated June 26, 1.900.

Application filed .Tune 30, 1899.

To @ZZ whom it may concern.-

Be it known that I, JOHN SHOUREK, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Bell-Ringing Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and usefulimprovements in gong-ringing mechanism; and the herein-described invention may be considered as a companion application to a certain application for Letters Patent filed by me December 7, 1898, Serial No. 698,530, for air-brakes.

This invention is particularly applicable and is especially designed to be used as an alarm-gong for street-railway cars and tramways; and the primary object of the invention is to construct a mechanism of the abovereferred-to class that may be operated by means of compressed air and one that will si'- multaneously operate with the brake mechanism.'

Another object of the invention is to provide novel means whereby a rapid vibratory movement is imparted to the tapper of the gong as soon as the brake mechanism is applied.

The invention further aims to construct a mechanism of the above-referred-to class that will contain n'o delicate parts that are apt to become out of order, but a mechanism that will be extremely simple in :its construction and highly eiiicient in its operation.

With the above and other objectsin view the invention finally consists in the novel construction, combination, and arrangement of parts to be hereinafter more particularly described, and specifically pointed out in the claims.

In deseribin g the invention in detail reference is had to the accompanying drawings, forming a part of this specification,v wherein like numerals of reference indicate corresponding parts throughout the several views, in which- Figure 1 is a side elevation of my improved gong-ringing mechanism with the casing removed, showin g the air chestv and cylinder in Serial No. 722,415. (No model.)

Fig. 13 is a top plan view of a portion of one side of the roof of acar, showing my gong-ringing mechanism as applied thereto Fig. 14 is a side View of a portion of a car, showing the connections between-the `brake-valve casing and the gongringing mechanism. Fig. 15 is a perspective View of the coupling device. Fig,` 1G is a side view of the coupling device, showing the same attached to the connections with the brakevalve casing and connecting the same to the ygong-ringing mechanism. Fig. 17 is aper- :spective View of the head -of the dischargepipe, showing the lugs to receive the fastening-hooks.

Referring to the drawings by reference-numerals, 1 indicates a suitable base, upon which ,is mounted my improved gong-ringing mechi anisrn andprovidedI with the openings 2 to;`

receive fastening means for removably securing the same to one jcar 3.

side of, the roofof thel The base 1 has formed integral therewith y 'at one side the extension 4t, provided with the upright or bell post 5, to which is secured the `bell G in such a manner as to allow of the tap-Y per-arm 7 to operate between' the bottom of the bell and the upper face of the extension 4. The tapper-arm 7 at its free end is curved upwardly, as at 8, and has mounted thereon the tapper 9, which is adapted to be brought into engagement with the inner face 'of the sides of the bell, as shown in dotted lines in Fig. 1. The inner end of the tapper-arm is pivotally secured to the post 10, and this end .of the tapper-arm is formed integral with the IOO ated from either car-platform. The brakelever 68 being operated will allow the air to pass to the auxiliary air-chamber 54, this chamber being connected to the brake-valve casing by a detachable coupling*for example, a construction set out in Figs. 15, 16, and l7the air passing upwardly7 through the pipe 56 and through the pipe 25 to the gongringing mechanism. As the A air passes through the pipe 25 the pressure thereof will remove one of the valves 27 from its seat and allow the air to pass in the union 24 and thence into the gong-ringing mechanism. Attention is called to the fact that when the pressure-of the air is decreased the action of the spring 30' against the openedv valve 27' will close the same. By arranging the pipes 25 26 in the manner shown and providing the same with the valves 27' allows for the operation of the bell from either end of the car, only one of the valves 27 being operated at a time to allow of the passage of air to the bellringing mechanism. The air passing into the air-chest by means of the inlet 25 (assuming that the valve is in the position as shown in full lines in Fig. l) will pass therefrom through the passage or port 37 into the cylinder and against the piston 27, operatin g the same to the position shown in dotted lines. At the same time the valve 29 will assume the position as also shown in dotted lines. It will be observed that the valve 29, owing to the recess 36, connects the passage 37 with the exhaust 39 on its forward movement, while the passage 38 is connected with the exhaust on the backward movement, the movement of the valve being in the opposite direction to that of the piston. This operation of the valve and piston will give an alternative reciprocating movement to the piston-rod and valve-stem to which the tapper is connected, and by the assistance of the sprin 4l a rapid vibratory movement will be given the tapper and cause the same to engage the inner face of the bell. When the flow of air is cut off, the operation of thevarious parts discon tinues.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- l. In a gong-ringing mechanism an airchest coapled to a suitable source of air-supply, a slide-valve operating therein, a valvestem connected thereto, a cylinder, a piston operating therein, inlet-ports arranged in the said cylinder,an exhaust-port arranged in said cylinder and adapted to be connected to each of the said inlet-ports alternately by the said slide-valve, a gong, a tapper therefor, an arm connected to said tapper, a bifurcated auxiliary arm formed integral with said tapperarm, a piston-rod connected to said auxiliary arm and said piston, and means for connecting said tapper-arm to the said valve-stem, substantially as set forth.
